The VMSpc software is always available for download on this site. Upgrades are free forever.

If you don't have the VMSpc Cables and Hardware you can still download and install the software. You can see for yourself how easy it is to customize VMSpc to your tastes. And when you are ready to "go live", give us a call at (888) 741-0259 and we'll set you up with everything else you need.

In order to make your installation as easy as possible, we will ask you what type of Diagnostic Plug you have in your Coach.
Refer to the document, SilverLeaf Electronics J1708/J1587, J1939, RV-C Wiring Diagrams to identify what the Diagnostic Plug looks like.

To get started, download the VMSpc Distribution CD v2.5 build 4 zip file onto your computer and unzip it into a folder on your PC. To start a fresh installation, run the Install program in that folder. If you are simply updating an existing installation, just copy the VMSpc.exe file into your existing VMSpc folder.
